Federal Excise Tax Information

Average Auxiliary Engine Fuel Consumption by Model

last updated in October of 2004

In the following, fuel usage and other information is shown for most twin-engine parking sweeper engines known to still be in operation as of late 2004. Models shown are for Schwarze machines, however check the the engine your sweeper uses and you will find it is probably on the chart. If not, check with your manufacturer and please let us know what model of sweeper and engine you are using so we can add it to this chart!

Calculations are based on the engine manufacturers' fuel consumption curves. Your actual fuel consumption may very due to factors such as engine wear and surrounding environmental conditions.

You will see that two values are shown for fuel usage: the 'required amount' and a 'maximum amount.' Unless you operate your sweeper at 90% of maximum RPM on a consistent basis, the first number is recommended for usage as your IRS fuel rebate multiplier. The IRS requires that a factor is included to allow for warmup and idling. So, the required fuel usage number would appear to be defensible since it includes such a factor. (Since most sweepers are operated at above minimum RPM during usage, the additional fuel used can be allocated to warmup and idling.)

If you do operate your sweeper at 90% of maximum RPM on a consistent basis, you may want to consider using the average of the two numbers to reflect the higher level of fuel usage that would occur. Since the resulting number is less than the maximum fuel used, it would also include a factor for idling and warmup.

If you do operate your sweeper consistently at such a high RPM setting, you should also check your flaps and other components for wear since it is unusual to need to operate a sweeper at such an RPM level in the usage for which it is designed.

It is strongly suggested that you consult with your CPA, attorney or other trusted tax professional for more information on filing for, and receiving, your fuel tax rebate for auxiliary engine fuel used by your sweeper. For ongoing reference, print this page.
